    Seasonal dynamics of a complex cheilostome bryozoan symbiosis: vertical transfer challenged

    Symbiotic associations are dynamic systems influenced by both intrinsic and extrinsic factors. Here we describe for the first time the developmental and seasonal changes of the funicular bodies in the bryozoan De...

    Reduction, rearrangement, fusion, and hypertrophy: evolution of the muscular system in polymorphic zooids of cheilostome Bryozoa

    Morpho-functional polymorphism of modules, also known as “division of labor”, is a widespread phenomenon independently evolving multiple times in the colonies of many aquatic invertebrates and invertebrate cho...

    First evidence of virus-like particles in the bacterial symbionts of Bryozoa

    Bacteriophage communities associated with humans and vertebrate animals have been extensively studied, but the data on phages living in invertebrates remain scarce. In fact, they have never been reported for m...

    Ultrastructural evidence for nutritional relationships between a marine colonial invertebrate (Bryozoa) and its bacterial symbionts

    Autozooids of the cheilostome bryozoan Aquiloniella scabra contain rod-like bacteria in the funicular bodies – the complex swellings of the funicular strands. Each funicular body contains symbionts in the central...
